The Vision Null Renderer can be used to calculate the data rate transferred across the system bus out of the capture card.

For 32bit operating systems:
Copy visionnull.ax into your %SYSTEMROOT%system32 directory.
Run the command console prompt with administrative permissions.
Type "regsvr32 visionnull.ax", click "OK" in the message box to successfully register the interface.
Attach your source to input 1 on your capture card.
Open graphEdit found within your DXSDK\Bin\DXUtils folder.
Insert a Vision capture source filter.
Open the "Filter Properties", right click the filter and select properties.
Press "Reset" in the dialog and ensure the width and height reflect the source resolution.
Close the "Filter Properties" dialog.
Open the "Pin Properties", right click the pin at the side of the filter.
Ensure that the default buffer is the source resolution for a 1:1 caputure/buffer.
Select your preferred frame rate, the default is set to the current input signal frequency.
Select one of the following colour space values:
RGB8	- 1 Byte per pixel
RGB565  - 2 Byte per pixel
RGB24   - 3 Byte per pixel
RGB32   - 4 Byte per pixel
Set the output buffer size, the 'Default Size' is the currently connected resolution, use this for 1:1 no scaling.
Close the "Pin Properties" dialog.
Insert the "Vision Null Video Renderer" filter, "Graph->Insert->Filters->DirectShow Filters->Vision Null Video Renderer".
Hold the left mouse button down over the Vision capture source filter pin and manually connect the arrow to the "Vision Null Video Renderer".
Select "Graph->Play".
Right click the "Vision Null Video Renderer" filter and select "Filter Properties" from the context menu.
The "Average frame rate achieved" field represents the frames delivered to the null renderer from the capture source filter on your system.
